6 Claims.

This invention relates to a machine, portable in nature, especially designed to trim railroad equipment journal brasses in carrying out the invention as shown and described in the copending application on Restoration of car journal brasses, filed in the United States Patent Ofice June 1, 1936, and bearing the Serial Number 82,858.

The present invention has for a primary purpose the provision of a specialized machine that may be operated by the repair men directly at the side of the car, the journal brasses of which are being removed for inspection and correction in accordance with said invention. It is the customary procedure to install an original journal brass having a Babbitt metal lining with a greater degree of curvature than that of the journal. After such a brass has been in operation under load for a period of time, it frequently happens that as the soft lining becomes rolled and pressed to conform to the curvature of the journal, some of this metal lining will be worked out on either or both edges of the brass to protrude in such manner that proper lubrication of the journal is prevented. Ordinarily such a brass, upon inspection, is removed from the journal and discarded as being unusable and a new brass is put in its place to be subjected to the same action.

By means of the present invention, this brass which is found to have the Babbitt metal overrunning the edges of the brass is placed in the machine of the type herein described and these edges are trimmed off to the required degree and then that same brass is returned to its own journal on which it was worn so that the advantages of the uniform bearing contact secured under the load conditions are retained, in addition to the effecting of a greatsaving in money by not having to discard that particular brass.

Not only does this machine trim the brass as indicated but it is arranged in such a form that the trimming may be done right at the side of the car while 'it is jacked up so that there is no danger ofv the brass from one particular journal becoming interchanged with the brass of another journal. Furthermore, the machine as conforming to the present invention is easily operated and adjusted so that it may be confined entirely to hand operation without having to bother with electrical, steam or air connections for power.

These and many other objects and advantages will become apparent to those working in this same art in the following description of one particular form of the invention as illustrated in the accompanying drawings, in which Fig. 1 is a rear perspective view of a machine embodying the invention in a position ready for use;

Fig. 2, a side elevation on a reduced scale showing the machine in a position for transportation;

' Fig. 8, a detail in vertical longitudinal sectio on the line 8-8 in Fig. 7.

Like characters of reference indicate like parts throughout the several views in the drawings.

A frame is formed comprising essentially the side rails I!) and H the rear supporting'legs l2 and it with braces l4, l5 extending from their lower ends forwardly and upwardly to the respective side rails; and a pair of front wheels l6 and I! carrying an axle l8 to which the forward ends of the side rails l0 and H are secured. Suitable handles l9 and 2B are secured to the rails iii and II and extend rearwardly to permit the lifting of the rear end of the frame thereby and pushingit about on the wheels l6 and IT in the manner of pushing a wheelbarrow, except that two wheels are provided in this instance for stability.

A pair of longitudinally spaced apart cross shafts 2| and 22' are rockably carried by the side rails. ill-and II and these shafts respectively carry the upwardly extending legs 22, 23 and 24, 25. Theupper ends of these legs rockably engage bed rails 26 and 21. The shafts 2| and 22 are mounted toward the rear portion of the frame so that the bed rails 25 and 2'! may be lowered and raised in parallel relation with the side rails l0 and II, as indicated in Fig. 2 where the solid lines indicate the parts-in their lowered positions and the dash lines, in theelevated positions.

This lowering and raising of these parts is accomplished and controlled by means of a gear segment 28 rockably mounted on the shaft 2| and fixed to a cross bar 29 inter-engaging the.

forward legs 22, 23. The peripheral teeth of the gear 28 engage with a Worm 30 which is mounted on a crank shaft 3! supported between a cross bar 32 and a bracket 33. Thus by turning the crank 3| by means of the handle 34, the gear 28 is revolved to carry the cross bar 29 therewith and thus lift the gears 22, 23 thereby. Through this shifting the bed plates 26 and 21 are obviously raised and lowered. The purpose of changing the elevation of these rails 26, 21 is to lower the mechanism to be carried thereon, as will hereinafter be described, so as to permit ease of transportation and to lower the center of gravity of such parts during the transportation, and at the same time permit raising of the parts to a proper working height for convenience of the operator.

Secured to the rails 23, 21 is a bed 35. This bed is generally U-shape in cross section and carries by the upturned ends a pair of guides 36, 31 having under and inwardly sloping faces serving to receive thereover and around a carriage 38.

This carriage 38 is shiftable along th bed by means of a spur gear 33, Fig. 4, meshing with a rack gear 48 secured to the underside of the carriage, the spur gear being mounted on a transverse shaft 4| turned by means of a hand wheel 42 at the side of the bed.

This carriage 38 has a brass holder 43 carried on its upper side in a manner to permit up and down and lateral movement after the brass 44,

Fig. 1, is clamped thereon. This holder is provided with a rear abutment 45 against which the rear end of the brass 44 may rest in an upsidedown position, the holder being provided with a transverse groove 46 at this abutment 45 to accommodate the projecting flange of the brass.

The rear end of the holder is hinged on a transversely extending pin 4'! which is carried across a head 48, Fig. 8. This head 48 is horizontally shiftable about a Vertical axis and has a cylindrical foot 49 slidingly entered in a like counterbore in the carriage 38 and is there retained against displacement by means of a screw 58 entering from the bottom of the carriage and screw-threadedly engaging thefoot 49. Thus the holder 43 may be lifted and lowered by its forward end to hinge on the pin 41 and may also be shifted by its forward end laterally over the carriage 38 by turning of the foot 49 on the carriage.

The brass 44 is secured in-position on the holder 43 by means of a jaw 51 slidingly engaging the forward end of the holder 43 in the nature of a carriage and arranged to be shifted back against the forward end of the brass so as to force the brass back into compressive engagement with the abutment 45. Movement of the jaw 5| is had by means of a screw 52 engaging therewith and connecting through a shaft 53, Fig. 5, with an operating crank 54, Fig. 4. The shaft 53 is carried through a head 55. This head 55 is fixed to the holder 43 to be shiftable therewith.

This head 55 is received between a pair of upturned legs '55 and 51 of a slide 58 which is guided in cross travel on the carriage 38 by means of a tongue 59 entering a slot 66 in the carriage. Transverse shifting of the slide 58 is accomplished by turning a hand wheel 8| which is mounted on a shaft 62 screw-threadedly passing through a leg 54 upturned at one side of the forward portion of the carriage 38 and interengaging with the carriage slide 58, as indicated in Fig. 5. The end of the screw shaft 62 has areduced neck portion and a head 63 therebeyond so as to receive a downturned lip of the slide 58 about that neck portion whereby the slide 58 will travel crosswise of the carriage 38 in that direction as the hand wheel 5| may be turned. This operation creates the horizontal shifting of the holder 43.

For vertical travel of the holder 43, the slide 58 carries a wedge 65 between the upturned legs 55 and 5! and this wedge is shifted laterally therebetween by means of a hand wheel 65 turning a screw shaft 61 passing through the leg 55 and screW-threadedly engaging the wedge 65. The under-face of the head 55 of that portion which fits between the legs 55 and 51 is inclined and bears against the top face of the wedge 65, whereby shifting of the wedge 65 laterally thereacross will lift the head 55 in one direction and permit it to drop in the other.

The desired degree of elevation of the work holder 43 resulting from manipulation of the hand wheel 63 is maintained by a securing screw 68 vertically passing down through the head 55 out of the path of the wedge 65 and screwthreadedly engaging the carriage 38 thereunder, Fig. 6. The head 55 is slotted so as to permit lateral shifting of the head 55 in relation to the screw for the lateral adjustment above indicated.

In the description so far given, mechanism has been described for the receiving and holding of the brass 44 in position to be reciprocated by the carriage 38 in a fore and aft travel along the bed 35 as produced by turning of the hand wheel 42.

Since it is the usual case that both edges of the brass must be trimmed, it is preferable that a pair of tool holders be provided in order that individual adjustment thereof as well as of the brass itself may be reduced in order to save time. In the form herein shown, in order to provide a mounting for the tool holders, a pair of standards 58 and 10 are secured to the respective sides of the bed 35 to extend upwardly therefrom and carry a guide bar 1| across the bed and spaced a distance thereabove. This bar H is provided with any typeof suitable guides, herein shown as having the top and bottom edges beveled to receive a tool carriage 12 thereon. This carriage 12 is caused to travel along the bar H by means of a shaft 13 carried by the upper ends of the standards 69 and 10 and turned by means of hand wheels 14 and I5, one on each end of the shaft 13. This shaft 13 has a central worm gear "I6 thereon which screW-threadedly engages through a projection I! mounted on the carriage 12.

This carriage '12 has mountedthereon on its forward side the spaced apart tool holders I8 and 19 each hanging from its respective screw shafts and 8! which extend upwardly through forwardly turned shoulders 82 and 83 to be 0D- erated by their own individual cranks 84 and 85. Each tool holder 18 and 19 carries a hingedly mounted block 85 onto which the tool 81 is clamped from the forward side, the block 86 being free to swing forwardly but restricted from swinging rearwardly by coming into contact in that direction by their respective holders. .These holders 18 and I9 are maintained in vertical alignment by engaging guides formed on the forward side of the carriage I2.

The individual tool 81 may be lowered into contact with the brass 44. and adjusted laterally for the proper size cut by means of either hand wheel 14 or 15 and also vertically for the depth of cut by means of the crank 84 or 85 as the case may be. Preferably, particularly since in the present form, the tool holders l8 and 19 are not individually adjustable one in relation to the other laterally, one tool 81 is maintained at an elevation so that it will not cut on the side of the brass opposite from that side to which the tool 81 is being adjusted. The cut is made by turning the hand wheel 42 to carry the brass 44 rearwardly past the tool, and then upon return forward travel, the tool 81 will be lifted out of the way without cutting. When the one edge is trimmed, then the other tool 81 may be likewise adjusted for the cut on the other side of the brass.

The trimmings cut from the brass may drop down on either side of the bed 35 between the rails 36 and 31 into a suitable collector pan 88 which is secured to the rails under the bed. Since the machine is to be used out of doors, a suitable housing 89 is provided consisting of side and end walls and over which a cover 90 may be placed, the cover being preferably hinged, as at 9|, Fig. 3, to the forward and end wall of the housing 89 so that the cover may be lifted up out of the way when the machine is in use and then dropped back down over the shaper for protection from the weather. Then when the machine is to be moved to the next scene of operation, such as the other end of the car or to the next car, or is to be carried back to the central shop, the entire shaper mechanism may be lowered down toward the rails l and H, as

above indicated.

Since the shaper necessarily has considerable weight, the cart for transporting it is preferably counterbalanced in some respect. I secure this counterbalancing effect by mounting a cabinet 92 forwardly of the axle l8 on a continuing part of the side rails l0 and II which are dropped down and extend forwardly under the cabinet as a means for its support. This cabinet 92 is provided with suitable compartments for carrying tools and extra brasses for the convenience of the operator. Such tools, and particularly brasses, have considerable Weight and since these articles are carried in the cabinet forwardly of the axle I8, there will be a counterbalancing efiect achieved thereby at the same time affording convenience to the operator.

While I have herein shown and described my invention in the one particular form, it is obvious that structural changes may be employed without departing from the spirit of the invention, and I, therefore, do not desire to be limited to that precise form beyond the limitations as may be imposed by the following claims.
